< first embodiment >

< overall Structure of report System >

The first embodiment of the present invention is explained below. Fig. 1 is a diagram showing an overall configuration of a notification system according to the present embodiment. The system includes a saddle-ride type vehicle 100, a portable terminal 200, an external device 300, an external device 400, and a wearable terminal 500. Moreover, it is not intended to limit the present invention, and other devices may be included.

The system detects a fall of the saddle-ride type vehicle 100, and a portable terminal 200 held by a rider of the saddle-ride type vehicle 100 collects various information and notifies it to a predetermined contact method by broadband wireless communication such as mobile communication (4G, 5G), and notifies it to an external device such as an emergency contact method (119 phone), a mobile terminal of an acquaintance, and an information storage server. These predetermined contact information can be set in advance. The external device 300 indicates a portable terminal in which an acquaintance is set as a predetermined contact address, and the external device 400 indicates a terminal of a fire department, a terminal of a hospital, or the like, for example, which are connected by a 119 telephone.

In the present system, the saddle-ride type vehicle 100, the portable terminal 200, and the wearable terminal 500 communicate by wireless communication (here, bluetooth communication) via a bluetooth (registered trademark) unit, respectively. The portable terminal 200 determines that the saddle-ridden vehicle 100 has fallen when the wireless communication between the saddle-ridden vehicle 100 and the wearable terminal 500 is interrupted. The portable terminal 200 performs this determination while the saddle-ride type vehicle 100 is traveling, receives information indicating the travel speed of the saddle-ride type vehicle, and performs the determination when the received travel speed is equal to or greater than a predetermined speed. When it is determined that the vehicle has fallen, the mobile terminal 200 acquires various information from the saddle-ridden vehicle 100, the wearable terminal 500, and the own device, and notifies a predetermined contact address of the information indicating the meaning of the fall and the acquired information. The wearable terminal 500 is a smart watch or the like worn by a rider of the saddle-type vehicle 100, and is capable of detecting biological information such as heart rate, blood pressure, electrocardiogram, blood oxygen, and arm movement of the rider, and transmitting the detected biological information to the portable terminal 200 by wireless communication (e.g., bluetooth communication). Information indicating that the communication between the saddle-ridden vehicle 100 and the wearable terminal 500 is interrupted is transmitted to the portable terminal 200 from the side of the saddle-ridden vehicle 100 and the wearable terminal 500 that is in communication with the portable terminal 200.

In this way, in the present system, the mobile terminal 200 collects various information, determines that the saddle-ridden vehicle 100 has fallen down, and notifies it by broadband wireless communication. This eliminates the need to separately provide a means for performing broadband wireless communication in the saddle-ridden vehicle 100, and makes it possible to appropriately perform notification.

The front wheel FW is turned by turning the wheel shaft 96 with the turning wheel of the handle 8.

The vehicle 100 includes a brake device 19F for braking the front wheels FW and a brake device 19R for braking the rear wheels RW. The

brake devices

19F and 19R are configured to be operable when the rider operates the brake handle 8a or the brake pedal 8 b. The

brake devices

19F and 19R are, for example, disc brakes. When the brake device 19F and the brake device 19R are not distinguished from each other, these will be collectively referred to as a brake device 19.

A headlamp 11 for irradiating light to the front of the vehicle 100 is disposed in the front portion of the vehicle 100. The headlamp 11 of the present embodiment is a two-lamp type headlamp unit including a right light irradiation part 11R and a left light irradiation part 11L in bilateral symmetry. However, a single lamp type, a three lamp type, or a double lamp type in which the left and right are asymmetrical may be employed.

The front portion of the vehicle 100 is covered with the cowl 12, and the side portion on the front side of the vehicle 100 is covered with a pair of right and left side fences 14. A windshield 13 is disposed above the cowl 12. The windshield 13 is a windshield for reducing wind pressure applied to a rider during traveling, and is formed of, for example, a transparent resin member.

A pair of left and right side view mirror units 15 are disposed on the sides of the cowl 12. The side mirror unit 15 supports a side mirror (not shown) for allowing a rider to view the rear.

In the present embodiment, the cowl 12 is composed of the cowl members 121 to 123. The surrounding member 121 extends in the Y direction to constitute a main body of the cowl 12, and the surrounding member 122 constitutes an upper portion of the surrounding member 121. The surrounding member 123 is disposed below and away from the surrounding member 121.

Between the surrounding member 121 and the surrounding member 123 and between the pair of left and right side flaps 14, an opening is formed to expose the headlamp 11, an upper edge of the opening is defined by the surrounding member 121, a lower edge of the opening is defined by the surrounding member 123, and left and right side edges of the opening are defined by the side flaps 14.

An imaging unit 16A and a radar unit 16B are disposed behind the cowl 12 as a detection device that detects a situation in front of the vehicle 100. The radar unit 16B is, for example, a millimeter-wave radar. The image pickup unit 16A includes: image sensors such as CCD (Charge Coupled Device) image sensors and CMOS (Complementary Metal Oxide Semiconductor) image sensors; and an optical device such as a lens that captures an image in front of the vehicle 100. The imaging unit 16A is disposed behind a surrounding member 122, and the surrounding member 122 constitutes an upper portion of the cowl 12. An opening 122a is formed in the surrounding member 122 to penetrate therethrough, and the image pickup unit 16A picks up an image of the front side of the vehicle 100 through the opening 122 a.

Radar unit 16B is disposed behind enclosing member 121. Due to the presence of the surrounding member 121, the presence of the detection unit (outside monitoring apparatus) 16 can be made inconspicuous when the vehicle 100 is viewed from the front, so that deterioration in the appearance of the vehicle 100 can be avoided. The enclosure member 121 is made of a material that can transmit electromagnetic waves, such as resin.

The imaging unit 16A and the radar unit 16B are disposed in the center portion of the cowl 12 in the Y direction when the vehicle is viewed from the front. By disposing the imaging unit 16A and the radar unit 16B at the center portion of the vehicle 100 in the Y direction, it is possible to obtain a larger imaging range and a larger detection range on the left and right sides in front of the vehicle 100, and it is possible to detect the situation in front of the vehicle 100 more reliably. Further, since the front of the vehicle 100 can be monitored uniformly in the left-right direction by one imaging unit 16A and one radar unit 16B, a configuration in which a plurality of imaging units 16A and radar units 16B are not provided and one unit is provided is particularly advantageous.

< control Structure of report System >

Fig. 4 is a block diagram showing a control configuration of the notification system according to the present embodiment, and only a necessary configuration related to the description to be described later is shown. The system includes a saddle-type vehicle 100, a portable terminal 200, an external device 300, an external device 400, an external device 600, and a wearable terminal 500. These structures are merely examples, and are not intended to limit the present invention. For example, the straddle-type vehicle 100, the portable terminal 200, the wearable terminal 500, and one external device may be used alone, or more external devices may be included.

The saddle-ride type vehicle 100 includes a control unit (ECU)101, a fall detection sensor 102, a communication unit 103, a storage unit 104, an electric horn 105, a vehicle speed sensor 106, a GPS 107, and an instrument panel MP. The control Unit 101 includes a processor represented by a CPU (Central Processing Unit). The storage unit 104 stores a program executed by the processor, data used by the processor for processing, and the like. The storage unit 104 may be incorporated in the control unit 101. The control unit 101 can be connected to the other components 102 to 106 via signal lines such as a bus, and can transmit and receive signals to control the entire saddle-ride type vehicle 100.

The dashboard MP displays various parameters and warnings of the saddle-ride type vehicle 100 to the rider. In the present embodiment, at least an operation target (second operation target) for stopping the notification is displayed on the dashboard MP. Further, if a microphone and a speaker are incorporated in the helmet, the stop operation of the notification may be controlled by voice and received by voice input.

The fall detection sensor 102 incorporates a pendulum member for detecting the inclination of the saddle-type vehicle 100, and when the pendulum member is inclined at an angle of about 60 to 70 degrees, the switch is turned on to output a signal. When these signals are input to control unit 101, control unit 101 determines that saddle-ride type vehicle 100 has fallen and stops the engine. Further, the control unit 101 notifies the mobile terminal 200 that the saddle-ridden vehicle 100 has fallen through the communication unit 103.

The communication unit 103 is a unit that performs wireless communication, and transmits and receives signals to and from the portable terminal 200 and the wearable terminal 500. The communication section 103 is, for example, a bluetooth unit that transmits and receives signals via short-range wireless communication (bluetooth communication). The communication unit 103 is activated when the saddle-ridden vehicle 100 is started up, and performs communication connection with the portable terminal 200 and the wearable terminal 500. The wireless communication may be a communication method capable of communicating within a predetermined range, such as wireless local area network LAN (Wi-Fi), bluetooth, near Field communication nfc (near Field communication), infrared communication, or the like. It is desirable that the communication range be set to, for example, a region including a radius of 5m to 20m from the saddle-ridden vehicle 100, so that communication with the mobile terminal 200 is ensured within a predetermined range even when the saddle-ridden vehicle 100 falls and the rider is separated from the saddle-ridden vehicle 100.

When communication between the saddle-ridden vehicle 100 and the wearable terminal 500 (hereinafter referred to as first communication or first communication state) is interrupted, the communication unit 103 transmits information indicating the interruption of the first communication to the portable terminal 200. In the present embodiment, whether or not each communication state is interrupted is determined based on the communication strength measured by the RSSI value, and when the measured RSSI value is equal to or less than a predetermined threshold value, it is determined that the communication state is interrupted. The threshold value is not particularly limited, and may be, for example, -60dBm, or-80 dBm, or-90 dBm, and a desired value may be set. As described above, it is determined whether or not the respective communication states among the saddle-ride type vehicle 100, the portable terminal 200, and the wearable terminal 500 are interrupted, but the determination criteria need not be unified. For example, the threshold value used for the determination may be different for each communication, and if the deterioration of the communication state can be detected, the method of measuring the communication state is not limited.

In the present embodiment, the electric horn 105 sounds and makes an alarm according to a situation in which the wireless communication between the saddle-ridden vehicle 100 and the wearable terminal 500 is interrupted (i.e., a fall of the saddle-ridden vehicle 100 is detected). Further, although an example in which only sound is used for the alarm is described, the present invention is not limited to this, and for example, the headlight 11, the turn signal lamp, or the like may be turned on or blinked instead of the alarm of the electric horn 105 or in addition thereto.

The vehicle speed sensor 106 detects the vehicle speed of the vehicle 100. The vehicle speed sensor 106 is a sensor that is supported by the front fork 95 and detects the amount of rotation of the front wheel FW, for example. The vehicle speed detected by the vehicle speed sensor 106 is stored in the storage unit 104. The storage unit 104 is configured to have a ring buffer, and the new vehicle speed information is replaced with the old vehicle speed information. The vehicle speed information stored in the storage unit 104 is periodically or aperiodically transmitted to the mobile terminal 200 via wireless communication. Further, the vehicle speed sensor 106 may include: acceleration sensors that detect other speeds related to the saddle-ride type vehicle 100, such as acceleration in the front-rear direction, the left-right direction, and the up-down direction of the vehicle 100; and an angular velocity sensor that detects the angular velocities in the roll direction, pitch direction, and yaw direction of the vehicle 100, and the vehicle speed sensor 106 stores various pieces of speed information in the storage unit 104. The speed, acceleration, and angular velocity of the saddle-type vehicle 100 are collectively referred to as information relating to the vehicle speed, but information indicating the moving speed of the saddle-type vehicle 100 is basically used in each process of the present embodiment. As described above, the information indicating the speed of the saddle-ridden vehicle 100 is periodically or irregularly transmitted to the portable terminal 200 via wireless communication, and is used as a criterion for determining whether or not to determine the communication state. The portable terminal 200 may be provided with a speed sensor, not shown, and the moving speed measured by the speed sensor may be used as the moving speed of the saddle-type vehicle 100.

The GPS 107 acquires the current position of the saddle-ride type vehicle 100. In the present embodiment, the GPS 205 provided in the mobile terminal 200 acquires the current position of the mobile terminal 200, and information indicating the acquired current position can be included in the notification performed when the fall determination is made. Here, instead of the current position of the portable terminal 200, the current position of the saddle-ride type vehicle 100 acquired by the GPS 107 may be used. In this case, when the fall determination is made in the present system, the communication between the mobile terminal 200 and the saddle-ride type vehicle 100 is interrupted, and therefore information indicating the current position of the saddle-ride type vehicle 100 is periodically or aperiodically transmitted to the mobile terminal 200, and information received immediately before the fall determination is used. Similarly, information indicating the current position acquired by a GPS (not shown) provided in the wearable terminal 500 may be used as the position information at the time of the fall.

Next, the configuration of the mobile terminal 200 will be described. The mobile terminal 200 is a mobile device such as a smartphone that is held by a rider of the saddle-ridden vehicle 100. The portable terminal 200 can be mounted on and fixed to the saddle-ride type vehicle 100 by, for example, a smartphone holder (not shown) provided in the saddle-ride type vehicle 100. It is considered that, when a fall occurs in this state, the distance between the mobile terminal 200 and the saddle-ridden vehicle 100 does not vary greatly, but the distance between them and the wearable terminal 500 worn by the rider is greatly separated, and the state of wireless communication between the terminals deteriorates. From this viewpoint, the portable terminal 200 according to the present embodiment determines that the saddle-ride type vehicle 100 has fallen, based on the reception of information indicating that the communication between the saddle-ride type vehicle 100 and the wearable terminal 500 is interrupted, from either the saddle-ride type vehicle 100 or the wearable terminal 500.

The configuration required for carrying out the present invention will be mainly described here. Thus, other structures may be included in addition to those described below. The portable terminal 200 includes a control unit 201, a storage unit 202, an external communication device 203, a display operation unit 204, a speaker 208, and a speed sensor. The external communication device 203 includes a GPS 205, a wireless device 206, and a notification section 207.

The control unit 201 includes a processor typified by a CPU. The storage unit 202 stores a program executed by the processor, data used by the processor for processing, and the like. The storage unit 202 may be incorporated in the control unit 201. The control unit 201 can be connected to

other components

203, 204, and 208 via signal lines such as a bus, and can transmit and receive signals, thereby controlling the entire portable terminal 200.

The control unit 201 notifies at least one of the external device 300, the external device 400, and the external device 600 via the wide area network using the notification unit 207 of the external communication device 203. The control unit 201 acquires various information via the GPS 205 and the wireless device 206. The GPS 205 acquires the current position of the portable terminal 200. This enables, for example, position information to be added at the time of notification. The wireless device 206 is capable of transmitting and receiving signals with the riding vehicle 100, the wearable terminal 500 via wireless communication. The wireless communication may be a communication method capable of communicating within a predetermined range, such as wireless local area network LAN (Wi-Fi), bluetooth, NFC, or infrared communication. The communication range can be set to, for example, an area including a radius of 5m to 20m from the saddle-ridden vehicle 100 or the wearable terminal 500. Further, communication connection with the saddle-ride type vehicle 100 is performed at the time of start-up of the saddle-ride type vehicle 100. The portable terminal 200 and the wearable terminal 500 are, for example, paired in advance, and are connected to each other by communication when the wearable terminal 500 is activated.

In the present embodiment, when acquiring information indicating that communication between the saddle-ride type vehicle 100 and the wearable terminal 500 is interrupted, the control unit 201 determines that the saddle-ride type vehicle 100 has fallen. The control unit 201 may measure the communication strength (radio wave strength) of the signal from the saddle-ridden vehicle 100 in the wireless device 206 by the RSSI value as described above, for example, and determine that communication is interrupted when the measured RSSI value is equal to or less than a predetermined threshold value.

Here, the higher the antenna output of the wireless communication for detecting a fall, the more likely the communication is to be interrupted, and the lower the antenna output, the more likely the communication is to be interrupted. In view of this, the control section 201 can adjust the antenna output according to the situation. For example, in the case where the straddle-type vehicle 100 establishes communication (first communication) with the wearable terminal 500, in order to more accurately detect a fall that occurs later, the antenna output of the first communication may be lowered. Further, for example, the antenna output may be varied according to the moving speed of the saddle-ride type vehicle 100. In this case, the faster the moving speed of the saddle-ridden vehicle 100 is, the lower the antenna output of the first communication can be made, from the viewpoint that the more likely it is to be in a dangerous state at the time of falling, the faster the moving speed is. For example, when determining that the communication is interrupted, the control unit 201 may instruct the saddle-ride type vehicle 100 or the wearable terminal 500 to increase the antenna output and determine whether or not the communication is interrupted again if the antenna output of the first communication is not the maximum, and may determine that the saddle-ride type vehicle 100 has fallen if the antenna output is the maximum. According to such a process, it can be determined that a fall has occurred when communication is not immediately determined to have fallen when it is determined that communication has been interrupted, but communication is still interrupted when the antenna output of the first communication is raised to the maximum output that can be confirmed. The adjustment processing of these antenna outputs may be performed autonomously by the communication unit 103 of the saddle-ridden vehicle 100 or the data communication unit 502 of the wearable terminal 500, or may be performed in response to an instruction from the control unit 201. In addition, these adjustment processes for the antenna output may be performed in the same manner in the wireless communication between the saddle-ride type vehicle 100 and the portable terminal 200 and in the wireless communication between the wearable terminal 500 and the portable terminal 200.

The display operation unit 204 is, for example, a touch panel-type liquid crystal display, and can perform various displays and accept user operations. An operation target for stopping the notification when a fall is detected is displayed in a selectable manner on the display operation section 204. The operation target may be displayed on the dashboard MP of the saddle-ride type vehicle 100 as described above, and used for the stop notification when the falling rider is active and trouble-free. Further, the user operation is not limited to being accepted by the operation target, and for example, instead of the operation target being operated, the notification may be stopped when the saddle-ridden vehicle 100, which has detected the communication recovery by the fall detection sensor 102, is lifted from the fall state. The period for which the stop operation for the notification is permitted may be dynamically changed in accordance with the vehicle speed (moving speed) at the time of falling. For example, if the vehicle speed is within 0km to 5km, the possibility of injury to the rider is low, and the possibility of the rider standing up the saddle-ridden vehicle 100 by the rider is high, so that a longer period can be set as the period for performing the stopping operation as compared with the case of falling down during traveling. For example, the control unit 201 may receive a stop instruction for the notification by voice input through a microphone (not shown), or may receive a stop instruction for the notification by detecting an operation such as pressing of a mechanical switch (for example, a handle switch) provided in the saddle-ridden vehicle 100.

The speaker 208 outputs an alarm sound upon detection of a fall. The alarm of the speaker 208 may be stopped by the above-described stopping operation of the rider, or may be stopped by an operation input to another stop button or the like. Further, when a stop screen of a later-described notification is displayed on the display operation unit 204 during a fall, it is desirable that the warning sound is output simultaneously with the display in order to inform the rider of the meaning of the stop screen, and that the warning sound is output at the maximum sound volume. The volume may be set in advance. In addition, not only the alarm sound, but also a voice-synthesized message (for example, "motorcycle fall accident occurs | rescue request" or the like is played after the alarm sound) may be played using the speaker 208. In the case of sound synthesis, it is possible to more clearly communicate what has happened to the surroundings.

The wearable terminal 500 is a portable terminal worn by a rider, such as a smart watch worn by the rider. The wearable terminal 500 includes a biological information detection sensor 501 and a data communication unit 502. The data communication unit 502 provided in the wearable terminal 500 transmits information indicating the first communication interruption to the mobile terminal 200 when the first communication is interrupted. The biological information detection sensor 501 detects biological information such as heart rate, blood pressure, electrocardiogram, and blood oxygen of the rider wearing the wearable terminal 500. These pieces of biological information may be periodically transmitted to the mobile terminal 200 by the data communication unit 502, or the latest data at that time may be transmitted in response to a request from the mobile terminal 200 when the saddle-ridden vehicle 100 falls down. In addition, it is desirable that, when a request is made from the mobile terminal 200, the biometric information is detected and transmitted in a fixed period thereafter in addition to the latest data at that time. This makes it possible to detect a change in the body of the rider during a fall. When a fall is detected, the rider of the saddle-ridden vehicle 100 can select whether to make a notification or stop the notification via the wearable terminal 500, which will be described later in detail with reference to fig. 11.

The external device 300 indicates a contact method set in advance, that is, a terminal to which a notification is given. The external device 300 is a portable terminal such as a smartphone, for example, and is a terminal held by an acquaintance in which a rider has registered in advance. The control configuration is the same as that of the mobile terminal 200, and thus the detailed configuration is omitted. The display operation unit 301 of the external device 300 displays the content notified by the portable terminal 200. The detailed display contents will be described later.

The external device 400 is a terminal that receives an incoming call notified by the notification unit 207, for example, an emergency contact address (119 phone call or the like). Here, the notification section 207 may output an automatic voice when the external apparatus 400 answers the incoming voice call. This is because it is assumed that the rider cannot communicate with the vehicle for some reason when falling. The automatic speech may be repeated multiple times, taking into account the hearing loss of the other party. For example, the notification unit 207 may display a switch button for switching from the automatic speech to the call made by the rider himself/herself on the display operation unit 204 or the like, with the call made by the automatic speech as a default setting. When the switching button is operated, the automatic voice is terminated and the voice call is switched to the normal voice call. The contents of the automatic speech include, for example: the voice is an automatic voice, the possibility of occurrence of a fall accident, the address of the place of occurrence, the time of occurrence, the speed and acceleration of the saddle-ride type vehicle 100 immediately before the accident, the name, age, blood type of the rider, the contact information of family, biological information, and the like.

The normal voice call may be performed by the portable terminal 200 or the wearable terminal 500. Since the portable terminal 200 may be separated from the rider during the fall, it may be set that a voice call is first attempted through the wearable terminal 500 and then a voice call is attempted through the portable terminal 200.

The external device 600 is an example of a data server of the present system, and stores various information transmitted from the mobile terminal 200. This information is used for accident investigation and the like. The communication method may be, for example, an electronic mail format, or may be a communication method capable of transmitting other information. The received information is stored in the data storage unit 601.

< communication connection of the present System >

Fig. 5A to 5C are diagrams showing communication connection relationships of respective devices in the notification system according to the present embodiment. As shown in fig. 5A, the mobile terminal 200 plays a central role of the present communication system.

The portable terminal 200 establishes wireless communication such as bluetooth communication with the communication unit 103 of the saddle-ridden vehicle 100 and the data communication unit 502 of the wearable terminal 500, respectively. Hereinafter, the communication (state) between the wireless device 206 and the communication unit 103 of the mobile terminal 200 is referred to as a second communication (state), and the communication (state) between the wireless device 206 and the data communication unit 502 is referred to as a third communication (state). The second communication establishes a connection at the start of the saddle-ridden vehicle 100 for transmitting and receiving information indicating the moving speed while running, the meaning when a fall is detected by the fall detection sensor 102, and various information. In addition, the third communication establishes a connection for transmitting and receiving the rider's biometric information and the like when the wearable terminal 500 is started.

The mobile terminal 200 can communicate with the external device 300, the external device 400, and the external device 600 via broadband wireless communication (fourth communication). The mobile terminal 200 notifies the external device 400 of various information such as position information, biological information, and vehicle speed to the external device 300 and the external device 600 by an emergency notification, for example, and an electronic mail.

In the present system as described above, when the first communication, which is the communication between the saddle-ridden vehicle 100 and the wearable terminal 500, is interrupted, information indicating the interruption is transmitted to the portable terminal 200 via the second communication or the third communication. Considering that one of the second communication and the third communication is interrupted in addition to the interruption of the first communication, the mobile terminal 200 can acquire information indicating the interruption of the first communication from either the second communication or the third communication.

Fig. 5B is a diagram showing the present system in the case where the first communication and the third communication are interrupted. This example is an example in which, for example, when the portable terminal 200 is fixed to the saddle-ride type vehicle 100, the first communication and the third communication are interrupted as a result of a fall. In this case, the portable terminal 200 receives information indicating that the first communication is interrupted from the saddle-ridden vehicle 100 via the second communication. Then, the portable terminal 200 transmits information including the biometric information of the rider at the latest time previously received from the wearable terminal 500 to the external device via the fourth communication, because the third communication is interrupted.

Fig. 5C is a diagram showing the present system in the case where the first communication and the second communication are interrupted. This example is where a rider, such as the riding vehicle 100, wears the portable terminal 200, and the first communication and the second communication are interrupted as a result of a fall. In this case, the mobile terminal 200 receives information indicating that the first communication is interrupted from the wearable terminal 500 via the third communication. Then, since the third communication is not interrupted, the mobile terminal 200 receives the biological information of the rider at the present time from the wearable terminal 500, and transmits information including the biological information to the external device via the fourth communication.

Whether the second communication or the third communication is interrupted is determined by the control section 201 in the same manner as the first communication. In this way, when the second communication or the third communication is also interrupted in addition to the first communication interruption, it is determined that the vehicle has fallen, and it is possible to more accurately detect the fall of the saddle-ridden vehicle 100 and shift to the notification process.

< processing procedure of Mobile terminal >

Fig. 6 is a flowchart showing a basic flow of processing performed when the mobile terminal 200 according to the present embodiment falls. For example, the CPU of the control unit 201 reads a program stored in the ROM (Read Only Memory) or the storage unit 202 into the RAM (Random Access Memory) and executes the program, thereby realizing the processing described below. The mobile terminal 200 according to the present embodiment periodically or aperiodically acquires information indicating the moving speed of the saddle-ridden vehicle 100, and starts the processing after S604 by acquiring information indicating the first communication interruption. The numbers following S indicate the step numbers of the respective processes.

First, in S601, the control unit 201 of the portable terminal 200 establishes a communication connection (second connection) with the communication unit 103 of the saddle-riding vehicle 100 via the wireless device 206 when the saddle-riding vehicle 100 is started. Further, when the wearable terminal 500 is activated, the control unit 201 establishes a communication connection (third connection) with the data communication unit 502 of the wearable terminal 500 via the wireless device 206. In S601, either the second connection or the third connection may be established first. Then, in S602, the control unit 201 determines whether or not information is received from the saddle-ridden vehicle 100 via the second communication connected in S601. If no information is received, the determination of S602 is repeated. Here, the control unit 201 receives information indicating the moving speed of the saddle-type vehicle 100, and advances the process to S603. In S603, the control unit 201 determines whether or not the moving speed of the saddle-ride type vehicle 100 is equal to or higher than a predetermined value. The predetermined value can be set to any speed value, and for example, the speed per hour can be set to 10km in order to detect a fall occurring during traveling. If the value is equal to or greater than the predetermined value, the process proceeds to S604 and waits until a fall is detected, and if the value is not equal to or greater than the predetermined value, the process returns to S602.

At S604, control unit 201 acquires information indicating that the first communication has been interrupted in order to detect a fall of straddle-type vehicle 100. In S605, the control unit 201 determines whether or not the antenna output of the first communication is maximum. The process proceeds to S607 when the antenna output is maximum, and proceeds to S606 when the antenna output is not maximum. In S606, the control unit 201 issues an instruction to increase the antenna output to the saddle-ridden vehicle 100 or the wearable terminal 500, returns the process to S604, and waits for the fall to be detected again. At S607, the control unit 201 executes the fall time processing, and ends the processing. The process of falling will be described in detail later with reference to fig. 8.

If it is determined that the fall has occurred when the second communication or the third communication is interrupted in addition to the first communication interruption, the control unit 201 in S604 detects that the second communication or the third communication is interrupted in addition to acquiring the information indicating the first communication interruption. That is, in S604, the process stands by until the first communication and the second communication or the first communication and the third communication are interrupted. In this case, it is determined in S605 whether or not the antenna outputs of the interrupted communication are all the maximum, and if all the antenna outputs are the maximum, the process proceeds to S607, and if not all the antenna outputs are increased, the antenna outputs whose outputs are not the maximum are increased in S606.

< Process for handling falling of saddle-ride type vehicle >

Fig. 7 is a flowchart showing a procedure of processing when the saddle-ridden vehicle 100 according to the present embodiment falls. For example, the CPU of the control unit 101 realizes the processing described below by reading out and executing a program stored in the ROM and the storage unit 104 to the RAM. The numbers following S indicate the step numbers of the respective processes.

First, in S701, when the saddle-ride type vehicle 100 is started, the control unit 101 of the saddle-ride type vehicle 100 establishes a communication connection for wireless communication with the portable terminal 200 and the wearable terminal 500 via the communication unit 103. Then, in S702, the control unit 101 stores the moving speed of the saddle-riding vehicle 100 acquired by the vehicle speed sensor 106 in the storage unit 104, and transmits the moving speed to the portable terminal 200 via wireless communication. The transmission may be periodic or aperiodic.

Then, in S703, the control unit 101 determines whether or not the communication connection with the wearable terminal 500, that is, the first communication is interrupted. If there is no interrupt, the process returns to S702. On the other hand, if the first communication is interrupted, the process proceeds to S704, and the control unit 101 performs a process when the vehicle has fallen down, and ends the process. The processing when the vehicle falls is, for example, processing for notifying the surroundings of the occurrence of a fall of the saddle-type vehicle 100, such as alarm processing for sounding the electric horn 105. When the electric horn 105 is to be sounded, the control unit 101 may stop the sounding by operating an operation target (similar to a stop button 1003 described later) displayed on the dashboard MP of the saddle-ridden vehicle 100. When the wearable terminal 500 can communicate with the control unit 101 after the fall has been detected, the control unit may stop the notification using a GUI (Graphical user interface) shown in fig. 10, which will be described later, to terminate the sounding process of the electric horn. In addition, in the present system, a situation may occur in which the first communication is interrupted but the second communication is not interrupted. In this case, the control unit 101 may perform the processing shown in fig. 7 in response to an instruction from the control unit 201 of the mobile terminal 200.

< details of the processing when the mobile terminal fell >

Fig. 8 is a flowchart showing the detailed procedure of the fall time processing at S607 of the mobile terminal 200 according to the present embodiment. For example, the CPU of the control unit 201 reads out a program stored in the ROM or the storage unit 202 to the RAM and executes the program, thereby realizing the processing described below. The numbers following S indicate the step numbers of the respective processes.

When the information indicating the first communication interruption is acquired in S604, the control unit 201 outputs an alarm sound with the speaker 208 in S801. In S802, the control unit 201 acquires information on the preset contact address at the time of falling from the storage unit 202. In S803, the control unit 201 causes the display operation unit 204 to display a notification stop screen 1000 including an operation target described later. A detailed report stop screen 1000 will be described later with reference to fig. 10. The order of the processing in S801 to S803 is not particularly limited, and may be any order.

Then, in S804, the control unit 201 determines whether or not the stop operation for the notification has been accepted by the operation target being operated. If the stop operation is accepted, the process proceeds to S808, and if the stop operation is not accepted, the process proceeds to S805. If the stop operation is not accepted within a period from the start of the display of the notification stop screen 1000 to the elapse of a predetermined time (for example, 30 seconds) for example, it is determined that the stop operation is not accepted, and the process proceeds to the notification process. As described above, the predetermined time period may be changed in accordance with the vehicle speed immediately before the fall. Further, although the case where the operation target for giving the stop instruction is operated for the notification has been described here, the present invention is not limited to this, and for example, the process of S808 may be executed after receiving the stop operation when the rider re-raises the fallen saddle-ridden vehicle 100. For example, when the communication with the saddle-ride type vehicle 100 is restored, it may be determined that the saddle-ride type vehicle 100 has been re-raised by using, as a trigger, a case where the signal input of the fall detection sensor 102 is stopped. In S808, the control unit 201 stops the output of the output alarm sound, and ends the process.

In S805, the control unit 201 acquires the biological information of the rider from the wearable terminal 500. In this case, the control unit 201 may acquire the latest time biological information acquired via the third communication as the biological information of the rider when the third communication is interrupted, and may transmit a request for transmitting the biological information to the wearable terminal 500 when the third communication is not interrupted. Then, in S806, the control unit 201 acquires the current position information via the GPS 205. Then, in S807, the control unit 201 notifies the preset contact address of the meaning indicating the occurrence of the fall, and notifies the preset contact address of the biological information, the position information, the vehicle speed information, and the like as necessary, and ends the processing. When a plurality of contact addresses are set, the notification is performed in sequence. For example, these notifications are sequentially given priority to the external apparatus 400, the external apparatus 300, and the external apparatus 600 as the emergency contact means.

< settings screen >

Fig. 9 is an example of a contact setting screen 900 displayed in the mobile terminal 200 according to the present embodiment. The setting screen 900 is displayed on the display operation unit 204. The setting screen 900 described below may be displayed on the dashboard MP so as to be operable in response to an instruction from the mobile terminal 200.

As shown in fig. 9, the setting screen 900 includes the following setting fields: an emergency contact 901, a contact setting 902 for telephone communication set by the user, and an email address setting 904 set by the user. The contact information can be input and set in each setting field. In the emergency contact information 901, "119" is set in advance as a default. The setting screen 900 is configured to further include an add button 903 and an add button 905 corresponding to the contact setting 902 and the destination setting 904, respectively. When each of the add buttons 903 and 905 is selected, a setting field of a contact address and a destination address can be added.

The setting screen 900 includes a confirmation button 906 and a cancel button 907. When the confirmation button 906 is selected, the contact information and the like set on the setting screen 900 are confirmed and stored in the storage unit 202. On the other hand, when the cancel button 907 is selected, the contact information and the like set on the setting screen 900 are canceled, and the setting information is not changed.

< Notification stop Picture (Portable terminal) >

Fig. 10 shows an example of a notification stop screen 1000 displayed on the mobile terminal 200 according to the present embodiment. The notification stop screen 1000 is displayed on the display operation unit 204. A screen similar to the notification stop screen 1000 described below is displayed on the dashboard MP so as to be operable in response to an instruction from the mobile terminal 200, but detailed description thereof is omitted.

As shown in fig. 10, the notification stop screen 1000 is configured to include the following displays: a display showing the meaning of notifying the contact information 1001 and the destination 1002 after a predetermined time (30 seconds in this case) has elapsed since the detection of the fall of the saddle-ridden vehicle 100, that is, the motorcycle; the selection of the stop button is prompted to stop the display of the notification without problems. The notification stop screen 1000 includes a stop button 1003 and a notification button 1004. When the stop button 1003 is selected, the mobile terminal 200 determines that the stop operation for the notification has been accepted, stops the alarm processing and the notification processing, and notifies the saddle-ride type vehicle 100 of the fact that the stop operation has been accepted. When the notification button 1004 is selected, the mobile terminal 200 starts the notification process without waiting for the predetermined time to elapse. The stop button 1003 is an example of a first operation target. The second operation target displayed on the dashboard MP of the saddle-ride type vehicle 100 is displayed in the same manner as the stop button 1003. Note that a button corresponding to the notification button 1004 may be displayed on the dashboard MP. It is desirable that the stop button 1003 continues to be displayed even after the predetermined time period has elapsed. This is to operate to stop the alarm when the rescuer arrives.

< Notification stop Picture (wearable terminal) >

Further, in the case where the portable terminal 200 is fixed to the saddle-ride type vehicle 100, it is considered that only the wearable terminal 500 is a terminal on the side of the rider when a fall occurs. In consideration of this situation, the same notification stop instruction as shown in fig. 10 may be performed by the wearable terminal 500. Fig. 11 is a diagram showing an example of a notification stop screen displayed in the wearable terminal 500.

In the example shown in fig. 11, since the falling of the saddle-ridden vehicle 100 is detected, a selectable GUI for notifying whether or not to be performed is displayed on the notification stop screen. Here, the wearable terminal 500 accepts selection of a saddle person for notification, or performs notification processing when a predetermined time has elapsed without accepting a stop instruction. The configuration of the wearable terminal 500 to receive an operation from the rider is not particularly limited. For example, the wearable terminal 500 may receive an operation from the rider by, for example, a touch operation on the stop button 1101 or the notification button 1102 on the notification stop screen 1100, may receive an operation from the rider by the switch 1103 corresponding to the stop process or the switch 1104 corresponding to the notification process, or may receive a selection operation of stop/notification by rotating the dial switch. Further, considering that the notification stop screen 1100 is easy to observe in correspondence with the size of the display, the notification stop screen 1100 displays only the stop button 1101 and the notification button 1102, but the same information as the notification stop screen 1000 of fig. 10 may be displayed in its entirety.

< notification Screen >

Fig. 12 is a diagram showing an example of a notification screen 1200 displayed on the external device 300 according to the present embodiment. The notification screen 1200 is displayed on the display operation unit 301. Note that the notification screen 1200 described below may be displayed by another external device.

The notification screen 1200 is, for example, the following screen: the address set by the destination setting 904 set in advance in the user setting of the setting screen 900 is notified and displayed on the external device 300. Also, various notification methods can be applied as a notification method to the external apparatus 300. For example, the screen information of the notification screen 1200 may be transmitted to the external device 300, or only various information such as position information and biological information may be transmitted together with the meaning indicating the fall. In addition, if an application associated with the present notification system is installed in the external device 300, the notification screen 1200 may be displayed on the application using the information, or may be displayed on an arbitrary browser screen. Alternatively, only messages and information may be received by email and displayed on an application program in the mailbox. Or may be displayed on the SNS application.

The notification screen 1200 includes: a message 1201 indicating the meaning of the rider of the ride-on vehicle 100 falling; a map 1202 representing the location of the fall; the rider biometric information 1203; and an outgoing voice to rider button 1204. These components can be individually selected or rejected according to the displayed application program.

A mark 1205 indicating the location of the fall on the map, the vehicle speed 1206 immediately before the fall, and detailed information 1207 of the location of the fall are displayed on the map 1202. The biological information 1203 shows, for example, an electrocardiogram, a heart rate, a blood pressure, and a blood oxygen. When the voice outgoing button 1204 is selected, the external device 300 makes a voice outgoing to the portable terminal 200.

< second embodiment >

< body abnormality detection processing for rider >

A second embodiment of the present invention is explained below. The information processing apparatus according to the first embodiment can determine that a fall has occurred from the first communication interruption, and can notify the external device of the fall. The control unit 201 of the portable terminal 200 according to the present embodiment determines whether or not a body abnormality occurs in the rider based on the biological information of the rider received from the wearable terminal 500 in addition to the above. Then, when determining that the body abnormality has occurred in the rider, the control unit 201 notifies the external device of the occurrence of the body abnormality by performing the same processing as that in the case where the fall has occurred in the first embodiment (for example, S807). In addition, when determining that the rider has a physical abnormality, the control unit 201 may decrease the output of the power source (engine) of the saddle-ridden vehicle 100. That is, the mobile terminal 200 according to the present embodiment determines that the rider is in a dangerous state similar to a fall when the rider has a physical abnormality, and performs various handling processes.

The control unit 201 according to the present embodiment determines whether or not a body abnormality has occurred in the rider based on the biological information. The biological information used here is heart rate, blood pressure, electrocardiogram, blood oxygen, etc., but is not particularly limited to this if the health state of the rider can be determined. When the biological information indicates an abnormal value, the control unit 201 determines that a physical abnormality has occurred. Here, the abnormal value in the biological information may be set in advance, or may be set based on a measurement value of the rider acquired from the wearable terminal 500 for a predetermined period (for example, a value that is different from an average value of the measurement values by a predetermined value or more is regarded as an abnormal value). The heart rate considered as an abnormal value by the control unit 201 may be, for example, 60 or less, 50 or less, or 40 or less, or 100 or more, 110 or more, or 120 or more. The maximum blood pressure regarded as an abnormal value by the control unit 201 may be 130 or more, 150 or more, 170 or more, or 100 or less, 90 or less, or 80 or less. The minimum blood pressure regarded as an abnormal value by the control unit 201 may be 90 or more, 100 or more, or 110 or more. The control unit 201 can be regarded as an abnormal value when the electrocardiographic waves indicating the electrocardiographic waves show abnormal fluctuations, and this may be a case where a change in characteristics of a known disease such as arrhythmia or electrolyte abnormality occurs in the electrocardiograph, or an abnormal value based on the electrocardiographic waves of the rider for a predetermined period. The concentration of the blood oxygen considered as the abnormal value by the control unit 201 may be, for example, less than 96%, less than 95%, less than 94%, less than 93%. In this way, the type of the biological information of the rider measured by the wearable terminal 500 is not limited, and when the biological information is a value of a general abnormality, it is considered that the body abnormality occurs in the rider, and the control unit 201 notifies the body abnormality by lowering the output of the engine.

The control unit 201 may determine whether or not a physical abnormality has occurred based on the information acquired from the wearable terminal 500, or the wearable terminal 500 may determine whether or not a physical abnormality has occurred and acquire information indicating the determination result. When the wearable terminal 500 makes a determination, the same processing as the determination made by the control unit 201 described above is performed.

Fig. 13 is a flowchart showing a procedure of abnormality detection processing of the mobile terminal 200 according to the present embodiment. For example, the CPU of the control unit 201 realizes the processing described below by reading out and executing the programs stored in the ROM and the storage unit 202 to the RAM. The numbers following S indicate the step numbers of the respective processes. The processing shown in fig. 13 is performed during standby until a fall is detected in S604 according to the first embodiment.

In S1301, the control unit 201 acquires the biological information of the rider. Here, the control unit 201 may transmit a signal requesting biometric information to the wearable terminal 500, or may refer to the latest biometric information received from the wearable terminal 500 at the current time. In S1302, the control unit 201 determines whether or not a body abnormality has occurred in the rider of the saddle-type vehicle 100 based on the biological information acquired in S1301. The process proceeds to S1303 if a physical abnormality occurs, and returns to S1301 if no physical abnormality occurs.

In S1303, the control unit 201 decreases the output of the engine 21 of the saddle-ride type vehicle 100. Then, in S1304, the control unit 201 acquires the current position information via the GPS 205 in the same manner as in S806. Then, in S1305, the control unit 201 notifies the predetermined contact method of the meaning indicating that the body abnormality has occurred in the rider and the value indicating the body abnormality, and notifies the predetermined contact method of the position information, the vehicle speed information, and the like as necessary, and ends the processing. The same processing as the notification processing in S807 of the first embodiment can be performed except that the notification processing in S1305 notifies information on the physical abnormality instead of indicating that a fall has occurred.

According to such processing, when a physical abnormality of the rider is detected while the saddle-riding type vehicle is running, the portable terminal can perform processing corresponding to the abnormality.

< summary of the embodiments >

The above embodiments disclose at least the following program, information processing method, and system.

1. The program of the above embodiment causes a second portable terminal (e.g., 200) capable of wireless communication with a saddle-ridden vehicle (e.g., 100) and a first portable terminal (e.g., 500) to perform the following steps:

a reception step (e.g., S602) of receiving, from the saddle-riding vehicle, information indicating a movement speed of the saddle-riding vehicle;

an acquisition step (e.g., S604) of acquiring information indicating a first communication state between the saddle-ride type vehicle and the first portable terminal; and

and a fall determination step (for example, S604) for determining that the saddle-type vehicle has fallen when the moving speed of the saddle-type vehicle is equal to or higher than a predetermined speed based on the information received in the reception step and when the first communication state is interrupted.

According to this embodiment, it is possible to detect a fall of the saddle-ride type vehicle 100 in the portable terminal 200 according to whether or not the communication between the saddle-ride type vehicle 100 and the wearable terminal 500 is interrupted. Since the mobile terminal 200 can determine the fall, the mobile terminal 200 can also notify the fall using the communication function of the mobile terminal 200 such as a smartphone.

2. In the above embodiment, the present invention further includes: a first communication state determination step (e.g., S604) of determining a second communication state, which is a communication state with the saddle-ride type vehicle; and

a second communication state determination step (for example, S604) of determining a third communication state which is a communication state with the first mobile terminal,

in the fall determination step, the fall determination step is performed,

when the first communication state is interrupted and the second communication state is determined to be interrupted by the first communication state determination step, or

When the first communication state is interrupted and the second communication state determination step determines that the third communication state is interrupted,

determining that the riding vehicle has fallen.

According to this embodiment, when communication from the portable terminal 200 to the saddle-ride type vehicle 100 or the wearable terminal is interrupted in addition to interruption of communication between the saddle-ride type vehicle 100 and the wearable terminal 500, it is determined that a fall has occurred, and thus the fall can be detected more accurately.

3. In the above-described embodiment, the first communication state determination step further includes a first lowering step of lowering an antenna output for performing wireless communication with the saddle-ride type vehicle when it is determined that communication is being performed with the saddle-ride type vehicle,

the second communication state determination step further includes a second reduction step of reducing an antenna output for performing wireless communication with the first mobile terminal when it is determined that communication is being performed with the first mobile terminal,

the acquisition step further includes a third reduction step of reducing an antenna output for performing wireless communication between the saddle-type vehicle and the first portable terminal when it is determined that the saddle-type vehicle is communicating with the first portable terminal.

According to this embodiment, the fall can be detected more accurately by reducing the output of the antenna after the start of communication.

4. In the above-described embodiment, the antenna output for performing wireless communication with the saddle-riding vehicle, the antenna output for performing wireless communication with the first portable terminal, or the antenna output for performing wireless communication between the saddle-riding vehicle and the first portable terminal is varied in accordance with the moving speed of the saddle-riding vehicle.

According to this embodiment, the accuracy of fall detection can be varied according to the risk caused by the moving speed of the saddle-type vehicle 100.

5. In the above-described embodiment, the antenna output for performing wireless communication with the saddle-ride type vehicle, the antenna output for performing wireless communication with the first portable terminal, or the antenna output for performing wireless communication between the saddle-ride type vehicle and the first portable terminal may decrease in accordance with an increase in the moving speed of the saddle-ride type vehicle.

According to this embodiment, the accuracy of fall detection can be improved as the moving speed of the saddle-type vehicle 100 increases, that is, as the risk of falling increases.

6. In the above embodiment, in the fall determination step,

in the case where the first communication state is interrupted and it is determined that the second communication state is interrupted,

if the antenna output for wireless communication with the saddle-ridden vehicle or the antenna output for wireless communication between the saddle-ridden vehicle and the first portable terminal is not the maximum, the antenna output is increased (e.g., S606),

determining that the saddle-ridden vehicle has fallen (e.g., S607) when an antenna output for performing wireless communication with the saddle-ridden vehicle and an antenna output for performing wireless communication between the saddle-ridden vehicle and the first portable terminal are maximum,

in a case where the first communication state is interrupted and it is determined that the third communication state is interrupted,

raising the antenna output when the antenna output for performing wireless communication with the first portable terminal or the antenna output for performing wireless communication between the saddle-ridden vehicle and the first portable terminal is not the maximum (for example, S606),

when the antenna output for performing wireless communication with the first mobile terminal and the antenna output for performing wireless communication between the saddle-ride type vehicle and the first mobile terminal are the maximum, it is determined that the saddle-ride type vehicle has fallen (e.g., S607).

According to this embodiment, when communication deteriorates, the output of the antenna can be increased, and thus wireless communication can be maintained in an effort, and when wireless communication cannot be maintained, falling can be detected.

7. In the above-described embodiment, in the fall determination step, it is determined whether or not the saddle-ridden vehicle has fallen based on the intensity of the wireless communication with the saddle-ridden vehicle, the intensity of the communication with the first mobile terminal, or the intensity of the communication between the saddle-ridden vehicle and the first mobile terminal.

According to this embodiment, the communication strength of wireless communication can be used as a criterion for determining falling.

8. In the above embodiment, the present invention further includes a notification step (e.g., S807) of transmitting a notification to a predetermined communication destination when it is determined that the saddle-ridden vehicle has fallen.

According to this embodiment, when the mobile terminal 200 detects that the saddle-ride type vehicle 100 has fallen, the notification can be made by using the communication function of the mobile terminal 200. Thus, the smartphone can integrate functions from the viewpoint of communication fee.

9. In the above embodiment, the communication apparatus further includes a reception step (e.g., S803) of receiving an operation to cancel transmission of the notification in the notification step.

According to this embodiment, the notification of the communication function can be cancelled without being required.

10. In the above-described embodiment, the accepting step includes a step of displaying an operation object for accepting an operation to cancel transmission of the notification.

According to this embodiment, in a fall that does not require a notification, the notification can be cancelled via the displayed operation target.

11. In the above-described embodiment, the present invention further includes a detection step (e.g., S806) of detecting a position of the saddle-ridden vehicle, the first portable terminal, or the second portable terminal,

when it is determined that the saddle-ride type vehicle has fallen, the notifying step further transmits the detected position of the saddle-ride type vehicle, the first mobile terminal, or the second mobile terminal to the predetermined communication destination.

According to this embodiment, since the position information indicating the position at which the saddle-type vehicle 100 falls is transmitted, the falling position can be smoothly specified.

12. In the above embodiment, the present invention further includes an acquisition step (e.g., S805) of acquiring biological information of a rider of the saddle-ridden vehicle,

when it is determined that the saddle-ridden vehicle has fallen, the notification step further transmits the acquired biological information to the predetermined communication destination.

According to this embodiment, it is possible to notify the communication destination of the biological information of the rider at the time of the fall, and it is possible to determine the urgency of the communication destination.

13. In the above embodiment, the method further includes: an abnormality determination step of determining whether or not the rider is abnormal based on the biological information of the rider acquired via the first terminal; and

and an abnormality transmission step of transmitting, when it is determined that the rider is abnormal, a meaning indicating that the rider is abnormal to the predetermined communication destination.

According to this embodiment, when a physical abnormality occurs in the rider while the saddle-ride type vehicle 100 is running, the notification can be made by using the communication function of the portable terminal 200. Thus, the smartphone can integrate functions from the viewpoint of communication fees.

14. In the above-described embodiment, the present invention further includes an instruction transmission step of transmitting, to the saddle-ride type vehicle, an instruction to reduce the output of the power source when it is determined that the rider is abnormal.

According to this embodiment, when a physical abnormality occurs in the rider while the saddle-riding vehicle 100 is running, the running speed of the saddle-riding vehicle 100 can be slowed down, thereby improving safety.

15. In the above-described embodiment, the first portable terminal is a terminal that can be mounted on the saddle-riding vehicle, and the second portable terminal is a terminal that is worn by a rider of the saddle-riding vehicle.

According to this embodiment, even when the portable terminal 200 is mounted on the saddle-ride type vehicle, it is possible to detect a fall of the saddle-ride type vehicle 100 depending on whether or not the communication between the wearable terminal 500 worn by the rider and the saddle-ride type vehicle 100 is interrupted.

16. The information processing method of the above embodiment is an information processing method for a second portable terminal capable of wirelessly communicating with a saddle-ride type vehicle and a first portable terminal, the information processing method including:
